Liquid fertilizer prepared taking biochar as raw material

Abstract

The invention discloses a liquid fertilizer prepared taking biochar as a raw material. A preparation method comprises following steps: 1, a bacteria bag, algae or water hyacinth, mung bean leaf or mung bean stem, liquid human and animal manure solution, EM bacteria agent, bentonite or river and pond mud are mixed to be uniform at a weight ratio of 1:1-2:1-2:4-6:0.1-0.15:2-3, an obtained mixture isintroduced into a fermenting tank for anaerobic fermentation, after fermentation, filtering is carried out so as to obtain a first fermented liquid; 2, green wheat straw, and corn stalk are smashed,green wheat straw, corn stalk, and the first fermented liquid are mixed to be uniform at a weight ratio of 2-3:1-1.5:10-15, and a second time of anaerobic fermentation is carried out; after fermentation, an obtained liquid is filtered so as to obtain a second fermented liquid and a first solid product; 3, the first solid product obtained in step 2 is pressed into bricks for further processing; 4,the bricks are introduced into a cracking furnace for cracking, and then are smashed so as to obtain biochar powder; and 6, potassium humate, the biochar powder, and the second fermented liquid are mixed to be uniform at a weight ratio of 0.1:1-1.5:10-18.

Description

technical field [0001] The invention relates to a liquid fertilizer, in particular to a liquid fertilizer prepared from biochar. Background technique [0002] As people pay more and more attention to the quality of life, organic crops have been chosen by more and more people. At present, plant branches, leaves, fruit peels, rhizomes, and human and animal manure are mainly used for retting, fermentation, and composting to produce organic fertilizers. Avoid the pollution of crops and soil by chemical fertilizers, and at the same time repair the soil damaged by chemical fertilizers before, so as to obtain organic crops, such as organic rice, organic vegetables, organic fruits, organic pasture, etc. [0003] At present, organic fertilizers are mainly applied in the form of solid fertilizers, which have a large volume and low effective nutrients under the same volume, which is not conducive to transportation and large-scale promotion. Of course, some organic fertilizers are appl...

AI Technical Summary

Problems solved by technology

[0003] At present, organic fertilizers are mainly applied in the form of solid fertilizers, which have a large volume and low effective nutrients under the same volume, which is not conducive to transportation and large-scale promotion.

Of course, some organic fertilizers are applied in liquid form, but due to the characteristics of organic fertilizers, a certain amount of water-soluble chemical fertilizers have to be added to them, which makes them not actually organic fertilizers, and the fertilizer effect is relatively short. , far less than solid fertilizer

[0004] In the prior art, the only way to improve the fertilizer efficiency of organic fertilizers and at the same time improve soil organic matter is to apply biochar, but biochar itself is insoluble in water, so it cannot be applied to liquid fertilizers
